General Description
The
SY89537L
integrated
programmable
clock
synthesizer and fanout is part of a precision PLL-
based clock generation family optimized for enterprise
switch, router, and multiprocessor server applications.
This family is ideal for generating internal system
timing requirements up to 700MHz for multiple ASICs,
FPGAs, and NPUs. These devices integrate the
following blocks into a single monolithic IC:
PLL (Phase-Lock-Loop) based synthesizer
Fanout buffers
Clock generator (dividers)
Logic translation (LVPECL, LVDS)
Five independently programmable output
banks
This level of integration minimizes additive jitter and
part-to-part skew associated with discrete alternatives,
resulting in superior system-level timing with reduced
board space and power. For applications that require
a zero-delay function, see the SY89538L.

Precision Edge
Features
Integrated programmable synthesizer with multiple
output dividers, fanout buffers, and clock drivers
Direct interface to crystal: 14MHz to 18MHz
Input MUX accepts a reference and a crystal
(XTAL) source
– Ideal for reference backup clock source or
system test frequency source
– Patent-pending unique input MUX isolates XTAL
and reference inputs minimizes crosstalk
Guaranteed AC performance:
– 87.15MHz to 700MHz output frequency range
(with RFCK at 16.6MHz)
– <100psPP total jitter
– <7psRMS cycle-to-cycle jitter
– <8psPP deterministic jitter
– <0.7psRMS crosstalk induced jitter
– <50ps bank-to-bank skew
Output bank synchronization control pin
LVPECL and LVDS outputs
TTL/CMOS compatible control logic
Five independently programmable output
frequency banks:
– Four differential LVPECL output banks
– One differential LVDS output bank with 3 output
pairs
Separate output enable for each bank
3.3V ±10% power supply (2.5V output capable)
Guaranteed over the commercial and industrial
temperature range (-40C to +85C)
Available in 44-pin (7mm x 7mm) QFN package
